Greenhouse Manual Ventilation

The Manual Sidewall Lift Crank rolls up the sides of the greenhouse to provide ventilation and access. In order to install sidewall ventilation systems, we recommend using the Jiggly Greenhouse® Snap-On Clamps and the Steel EMT Coupling. Proper ventilation in a greenhouse or any outside enclosure is vital for a healthy, crop-yielding operation; these economical products will help you grow the best possible crops for a minimal cost.
